Abstract (en)

[origin: WO2013175138A1] The subject of the invention is in particular the dynamic monitoring of distances, in particular of memory access distances, in an NUMA type system comprising a plurality of processors, a local memory being associated with each processor of said plurality of processors. After having obtained (210) at least one NUMA distance between at least one first processor of said plurality of processors and a local memory associated with at least one second processor of said plurality of processors, said at least one NUMA distance obtained is stored (220) in place of at least one NUMA distance, previously stored, between said at least one first processor and said local memory associated with said at least one second processor, said at least one NUMA distance stored being usable directly by the operating system of said NUMA type system.
